MOLDBQARD.

Specification of Letters Patent.

Patented Feb. T2, 191%.

Application filed January 28, 1914. Serial No. 814,484.

To (ZZZ u'itom 2'25 may concern Be it known that I, LOUIS H. Kxocnn, a citizen of the United States, residing at Martin City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mold boards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

This invention relates to plows and cultivators, and one of the principal objects of the invention is to provide a mold board or cultivator tooth or shovel having an undulating or corrugated surface, designed to break up the mold or furrow slice as it passes over the mold board or cultivator shovel.

Another object of the invention is to provide a mold board having a corrugated or undulating surface for breaking up the mold. and means for bracing said mold board from the landside bar.

These and other objects may be attained y means of the construction illustrated in the accompanying drawings, in which,

Figure 1 is a bottom plan view of a plow made in accordance with this invention,

Fig. 2 is a side elevation of the same looking from the land side,

Fig. 3 is a rear elevation of the same,

Fig. 4 is an edge view of a cultivator shovel or tooth. and

ig. 5 is a perspective view of the same.

Referring to the drawings, the numeral 1 designates a mold board provided upon its outer surface and throughout its entire length with a series or number of corrugations or undulations 2. These corrugations or undulations extend transversely of the mold board and provide horizontally disposed alternate depressions and elevations. The undulations or corrugations may be formed in the outer surface of the mold board and if the latter is made of thin metal, the corrugations will show upon the innor side as well as upon the outer side. However, in casting the mold board, the outer surface may be corrugated while the inner surface may be perfectly plain and to follow the curve of the mold board without the corrugations being formed in the under side thereof.

The landside 4 which is formed integral with plow point 3 has connected to it the v the top down, and

landside bar 5, said bar being connected to the landside 4 by a single bolt 6. Formed integral with the landside bar 5 is a brace 7 which extends across and is curved to support the mold board, said brace being secured to the mold board by a bolt 8. A brace 9 formed integrally with the landside bar 5 extends straight across to brace the point at the line or junction of the mold board and point, while an integral inclined brace 10 extends from the mold board and is joined with the brace 9 at the point 11. Bolts 12 extend through the brace 9 for con-v necting the plow point. and mold board to the same.

As shown in Figs. 4 and 5, the numeral 13 designates a cultivator shovel or tooth having a corrugated or undulated surface 15. The undulations may be separated by substantially plain portions 16, and the undulating portions 15 may be slightly flat upon the outer side, as shown more clearly in Fig. 4.

A mold board or cultivator shovel having a corrugated surface will have a tendency to break up the furrow slice or mold as it passes from the bottom to the top of the mold board or shovel. furrow slice as it travels from the plow point or shovel point to the first depression in the mold board will break from the bottom up. lVhen the furrow slice enters the first depression it is caused to again break. at this time from as the slice has not as yet been lifted high enough to let it roll over it is held against the soil toward the team. As the furrow slice leaves this depression and travels over the adjacent elevation, it is again broken from the bottom up, and after traveling over this elevation and entering the next depression it begins to turn or roll over. during which turning or rolling over the furrow slice is broken in the reverse directions. Furrow slices broken up in this way require but one harrowing to prepare the soil for planting.

arious changes may be made in the details of construction without departing from the spirit and scope of the invention as defined in the claims.

\Vhat is claimed is 1. A mold board provided throughout its entire length with alternate depressions and elevations extending transversely to the direction of the movement of the furrow slice, said depressions and elevations providing a.

si rface adapted to break up the furrow s 1ce.

2. A plow or cultivator shovel having a mold board provided throughout its entire length With comparatively large depressions and elevations, said depressions and elevations extending transversely of the mold board and being alternately arranged, and said depressions and elevations providin the mold board with a SIIIfflGE adapted 10 to reak up a furrow slice.

In testimony whereof I affix mysignature in presence of two Witnesses.
